WATCH-CASE.y

LPEGIFICATION forming part of Letters Patent No. 340,814, dated April27, 1886.

(No model.)

Bc it known that I, DANIEL OfI'Ii-tui-t, ot" XValtha-m, in the countyot' Middlesex and State of Massachusetts, have invented certain new anduseful Improvements in W'atclrGases, of which the following is a full,clear, and exact description.

This invention relates more particularly, although applicable towatch-cases ofother construction, as will hereinafter appear, towatchcases in which the movement-ring is jointed or hinged within thecase centeror shell, so as to be capable of being swung into and outthereof, and watch-cases of this character are more particularly k nownin the trade as Fitch wat eli-cases, and are embraced in Letters Patentot' the United States issued to Ezra t). Fitch, dated April 22, 1879,No. 21st-,642, to which reference is hereby had for a more fulldescription thereof.

This invention consists ofa movement-ring which is hinged or Kjointedwithin thc case center or shell, so as to be capable of being swung intoand out thereof, and is provided with a tlange overlapping the frontside ot' the case center or shell, and all otherwisesubstantially ashereinafter described.

In the drawings, all on an enlarged scale, forming a part of thisspecification, Figure l is a central transverse section of a watcheasehaving a movementring jointed or hinged within a case center or shelland provided with a vflange overlapping the front side of thccasecenter. Fig. 2 is a face view of the watch` case of Fig. Ll with thecrystal and llat bezelring detached, Figs. and t are transverse sectionsin detail and at one side of a watchcase, showing a modification, aswill hereinafter appear.

In the drawings, A represents the ease center or shell, formed, asshown, in one seamless piece of aconcave shape,open at one side-thefront IB--and closed at its other side-the back C-and all so as to besuitable to receive a watch-moronient carried by a ring, I), which(Figs. l and 2) is hinged orjointet'latone side,

responding shoulder, g, around the inner periphery ofthe ease-center A.

rlhe construction of the case center or shell A above describedconstitutes no part of this invention, and therefore needs no furtherdescription herein, it being deemed sufficient to observe that it is insubstance the same as described and shown in the Letters Patent beforecited, and to which reference is hereby had for a more particulardescription thereof. rlhe inove1nentring D has ailauge, H, surroundingit at its outer portion and in position to ovcr lap the front face ofthecase-ccnterA or riser (i thereat, and this ilange preferably is ofsufficient width to conceal by its overlap above stated the hinge orjoint lC of themovementi-ing l) and the slot J, usually made in the easecenter or shell to receive the handsetting lever of thewat-rh-niovenient, and also the recess or cavity K in the wntclreasecenter, to allow ofthe insertion of the thumb-nail to swing thewatclrmovement ont of thc easeeenter, turning by the hinge or joint E ofthe movement-ring upon -the ease-center. The tlange l'l may be made inone piece with the move1nentring, or in a piece separate there- Vfromand attached thereto by screws or solder or otherwise, and preferably seas to be,when so attached,practically of one piece therewith. Themovement-ring andr tlange may be of ditv ferent metals, the llange, asit is exposed, pref erably being made ot' a metal corresponding to themetal of which the exposed portions of the watch-case are made.

In order to allow themovement-ring having a flange, as described, to beswung upon its hinge or joint so as to place it and the watchmovementcarried by it in or out of the case center or shell, thecasc-eenterorshell andthe supplemental ring F, il' one is used, is cutout or removed, as at L, back of the hinge orjoint.

rIhis invention is to bein no way limited to any particular constructionot' the hinge or joint of the movement-ring within the ease center orshell, nor to any particular construction ofthe case center or shell,the invention in substance consisting of amovement-ring which is hingedor `jointed within the case center or shell, and is provided with atlangc for overlapping said shell at its front, substantially asdescribed.

rIhe supplemental ring, shown in Figs. 3 and I OO 4 of the drawings,-andwhich surrounds the 1novement-1ing and has the movement-ring hinged orjointed to it, of itself forms no part of the present invention, itbeing the subjectmatter of a separate application for Letters Patent ofeven date, andSerial No. 183,983.

Having thus described inyinvention, whatl claim, and desire to secure byLetters Patent, 1s-

In a watch-ease, the combination of aniovement ring 0r band surroundingand containing` the Watch-movement and having a iange surrounding it, aease center or shell, and a hinge or joint covered by the flange ofmovementring and joining same to case-center, which is out away for thepassage of the fiange of movement-ring in the swing of said ringen itshinge, substantially as described, for the purpose specified.-

In testimony whereof I have hereunto set my hand in the presence of twosubscribing Witnesses.
